Shazam :
I have this interface:
public interface RestService {
//other methods
}
and this interface which extends RestService:
public interface NewRestService extends RestService{
void downloadPOD(String baseUrl, String orderNo);
}
My Implementation:
public class NewRestServiceImpl implements NewRestService {
public void downloadPOD(...);
//other method implementations
}
When I do this, it says
downloadPOD()is undefined:
@Autowired
private RestService restService;
...
restService.downloadPOD(...)
Please enlighten me. Thanks
Andronicus :
It's because downloadPOD method is not defined in the RestService interface. If you're sure the right implementation will be injected, you can cast the bean:
@Autowired
private RestService restService;
((NewRestService) restService).downloadPOD(...)
Or if you need to use the api of the implementation, that is not in the interface, maybe it would be better to simply inject NewRestService or NewRestServiceImpl:
@Autowired
private NewRestService newRestService;
